Maptapper
« on: January 08, 2025 »
Hi Guys - and a happy new year!

Anyone of you is familiar with maptapper and ripping multi-bitplane stuff from Amiga ?

I'm working on the Accession (https://www.youtube.com/watch?v=vQUcP-QF-hg)  Intro-Remake and I would love to use the original graphics from the Intro, but I'm really struggling to assemble the bitplanes..

Cheers.

doesn't the second image vital posted have the iso-spherical sprite sheet at the bottom? it just needs to be cropped in to its own image.

[EDIT]...

seems not.

i thought i would download maptapper and the amiga intro in attempt to check out what you are ripping... holy cr-p what a mess that thing is, and i am confused asf on what to do with it. i loaded in the intro, then pressed some keys, it changed the graphics on screen, but it was just all garble the entire way... yeh good luck with it (as i have no clue).

[EDIT]...

welp, after a quick watch of a maptapper tut... i understand how to rip amiga textures/sprites now. and yeh i was doing it wrong from the get-go, so no wonder it wasnt working for me. heh. g/l with it all.

I assume you know most of this, but since I'm horrible at explaining I'll just write down what I did

First off, we seem to have two different versions of the intro, as my graphics is at a different place in memory and the copper pointer is also at a different place, I will assume you have a full save-state and not a raw ramdump, and just use your pointers here.

This icosphere graphics has a bit special layout, which is why it was harder to rip.

Looking at your image from your initial message you can see that the graphics is laid out in rows:

row 1: bitplane 1
row 1: bitplane 2
row 1: bitplane 3
row 1: bitplane 4
row 2: bitplane 1
row 2: bitplane 2
row 2: bitplane 3
row 2: bitplane 4
et.c

This is why it was a bit different from ripping normal graphics

You already have the address of the start of the graphics: $5f000

Width: 352
Height: 32 <- this is the height of each animation step

At this time you should just set bitplanes to 4, since you can see in your screenshot that there are 4 rows before the next "row" of new graphics,
the colors will look horrible right now, set the "stop at line" to $33, press "Process" and it should extract the colors

Then, increase the "Rip Height" to 336..

Hope this help, just ask if I missed something :P

Ok, I'll try that again some time.. this won't be my last remake.

Thanks for taking the time to write down such a detailed explanation.

Cheers.
